“That’s probably the first time anyone’s tap-danced in the Temple of Dendur,” figured former “Gossip Girl” star Zuzanna Szadkowski at the Metropolitan Museum on Wednesday night during the Young-Arts New York gala.

Hoofer Demi Remick, one of YoungArts’ talented alumni, had just performed for a crowd that included legends Plácido Domingo and Mikhail Baryshnikov, YoungArts board members Agnes Gund and Sarah Arison, and guests Salman Rushdie — with latest girlfriend Laura Gomez Eastwood — and Benjamin ­Bronfman.

The night’s emcee, Szadkowski’s also a YoungArts alum who met her best friend, “Girls” star Andrew Rannells, when they were both students in the program.
